"It has no rhyme or reason, no particular time of day, no gender, no race, any of that," said detective Derek Spencer of the Missouri City Police Department. "It just seems that random. ... That is very concerning and scary."

Police said the attacks started at 7 p.m. on Tuesday, Feb. 17, when a gunman in a dark sport utility vehicle tried shooting at a 21-year-old college student. The gun jammed and the victim ran away.

About a half an hour later, 34-year-old Pak Ho was shot and killed nearby. He told police about a dark SUV before he died.

The third attack happened three hours later, police said.

Savalas Holmes said he saw a black Jeep Cherokee before he was shot near the thigh.

"He pulled right up on side of me. Window down already, already had it on his mind what he wanted to do," Holmes said. "That's when I turned to run. That's when he shot me."

Holmes said 1,000 thoughts ran through his head: "Am I losing too much blood? Am I going to collapse here?”

Hours after Holmes was attacked, a 50-year-old man was shot at a bus stop 15 miles away.

Another attack happened at 7:30 a.m. Sunday, when police said a person was shot in the arm and stomach.

The suspect is believed to be in his early 30s, with a stocky build, light mustache and a beard.

"We want to try to bring this person to justice for those family members and the rest of the community where they don't have to live in fear," said detective Andy Robb of the Missouri City Police Department.
